Product Overview
The Kitchen Mama Auto Electric Can Opener is a cordless handheld kitchen appliance designed to remove metal can lids without manual turning. Model CO1100-R operates from four AA alkaline batteries and moves around the rim of a can after the user activates its control button. The cutting mechanism separates the lid along the side of the can rather than cutting downward through the top surface.
The opener uses a stainless steel blade and an ABS plastic housing. Its side-cutting method is intended to leave a smoother edge than conventional top-cutting mechanisms. A magnet assists with holding or lifting the separated lid after cutting. Unlike Kitchen Mama models with automatic stopping, this version requires the control button to be pressed again to stop operation.
The cordless design allows the opener to be placed directly on compatible cans instead of requiring the can to be positioned against a countertop appliance. It is intended primarily for standard household food cans and may reduce the gripping and twisting motions associated with manual can openers.

Common Uses
The opener is designed for opening compatible household food cans without manually rotating a handle. It may be used during routine meal preparation for canned vegetables, fruits, soups, sauces, beans, and similar packaged foods.
Because the motor performs the cutting motion, this type of opener can also reduce the gripping and wrist rotation required by traditional manual openers. The cordless format allows it to be stored in a kitchen drawer or cabinet when not in use.
Maintenance and Care
- Wipe the exterior with a dry or slightly damp cloth when cleaning is needed.
- Do not immerse the opener in water.
- Do not place the appliance in a dishwasher.
- Avoid allowing water to enter the motor or battery compartment.
- Keep the cutting mechanism free from visible food residue.
- Remove depleted batteries and install replacements with the correct polarity.
- Store the opener in a dry location when it is not being used.
Safety Information
- Keep fingers and other objects away from the blade and drive gear during operation.
- Position the can rim correctly between the cutting blade and metal gear before activating the opener.
- Do not immerse the motorized appliance in water or other liquids.
- Use batteries with the polarity shown inside the battery compartment.
- Although the side-cutting mechanism is designed to produce smoother edges, separated lids and cans should still be handled carefully.

Compatibility
The opener is designed for a range of standard-sized household food cans. Proper operation requires a can rim that can fit between the opener’s blade and drive gear.
Can construction and rim shape vary among containers. Unusual, damaged, heavily dented, or nonstandard containers may not engage the cutting mechanism correctly.
Frequently Asked Questions
How can I identify this specific Kitchen Mama can opener?
The red version covered on this page is identified by model and manufacturer part number CO1100-R. These identifiers are more precise than relying only on the product’s appearance.
Does this model stop automatically?
No. This version uses button-controlled stopping. The user activates the opener to begin cutting and presses the control again to stop it after the cutting cycle.
Does the opener need to remain plugged into an electrical outlet?
No. It is cordless and receives its operating power from replaceable batteries.
How is the opener positioned on a can?
The opener sits on the top edge of the can. The rim must be positioned between the cutting blade and the metal drive gear before operation begins.
Does it cut through the top surface of the lid?
The mechanism cuts around the side of the rim rather than following the conventional top-cutting method used by many manual openers.
Why might a lid remain attached after it has been cut?
Some lids can remain in place because of the seal or pressure inside the container. A lid that has already been separated may need to be gently lifted rather than cut a second time.
Can the opener be washed under running water?
No. The appliance contains electrical and mechanical components that should not be submerged or exposed to running water.
Can it be cleaned in a dishwasher?
No. The motorized opener is not intended for dishwasher cleaning. Surface wiping with a dry or slightly damp cloth is the documented cleaning method.
Is installation required?
No permanent installation is required. The user installs the required batteries and positions the opener directly on the can during use.
Is this the same model as the Kitchen Mama Auto 2.0?
No. Auto 2.0 is a later product in the manufacturer’s electric can opener family and should be treated as a separate model.
Buying Considerations
This model uses replaceable AA alkaline batteries rather than a rechargeable internal battery or household electrical cord. Battery availability and replacement frequency are therefore relevant ownership considerations.
The unit is a handheld opener rather than a freestanding countertop appliance. Users should also consider the types and shapes of cans they normally open because unusually shaped or damaged rims can affect the operation of side-cutting mechanisms.
Model identification is important when comparing Kitchen Mama openers because several generations have different battery requirements, control methods, sizes, and stopping functions.
Customer Feedback Summary
This section summarizes recurring themes found in publicly available customer feedback and independent product evaluations. These observations are generalized user reports and are not verified technical specifications.
Frequently reported positive themes include reduced hand effort, straightforward operation, cordless convenience, and smoother can edges compared with many conventional top-cutting openers. Users with limited grip strength are among those who commonly report that the motorized design reduces the physical effort involved in opening cans.
Reported limitations include operating noise, the physical size of the handheld unit, and occasional difficulty installing or replacing batteries. Some users also describe a learning period for correct placement on the can rim. Performance may vary with unusually shaped, damaged, or irregular can edges.
